SEAT-REGISTER.

Specification of Letters Patent.

Patented May 1 1,1909.

Application filed September 7, 1907. Serial No. 391,803.

To all whom it may concern:

Be it known that we, WILLIAM BARR and Philadelphia and State ofPennsylvania, have invented certain new and useful Tmprovements inSeat-Registers, of which the following is a specification.

This invention relates to registering devices for seats adapted to beoccupied by persons.

The object 01 the invention is to provide a simple and eflicient meanswhereby the num ber of times a seat is occupied may be registered, andto this end the invention consists in the novel construction andcombinations of parts hereinafter described and particularly pointed outin the claims.

Figure 1. is a front elevation 01' a chair having our improved seatregister applied thereto. on the line aa of Fig. 1. 3 is a sectionalview as on the line 12-4 01' 2. Fig. 1 is a sectional view of thepneumatic cushion. Fig. 5 is a detail oi the means limiting the upwardmovement of the seat.

ii "e have illustrated our invention herein as applied to a form. o'l'chair or scat commonly used by boot-blacks. This seat comprises a casingforming the body 1 ol the chair, a l'oot rest 2, and a step leading tothe foot rest. Rising from the body 1 ol the chair are the usual armrests 1 and back The back of the seat 6 is pivotally connected as at 7to the casing, and the back 01' the the casing as at 9, so that saidseat and top may be raised and lowered on their pivotal The downwardmovement of the top of the step 3 is limited by a bracket 39 secured tothe interior of the casing, and the downward movement 01' the seat 6 islimited by a bracket 40 secured to the interior of the casing. Theupward movement 01' the top 01' the step 3 is limited by a pin 41.engaging the wall o'l' an opening in a bracket 42 secured to the top 01'the step 3, and the upward movement 01' the seat 6 is limited by a pin13 engaging the pivoted link 44; depending from a bracket on the bottomof the seat 6.

The seat 6 is held normally raised on its pivotal connection by theaction of a spring.

10 arranged within a socket in the casing, and acting upon the bottom ofthe forward portion of the seat 6. Projecting downi g and the bracket13. Fig. 2 is a sectional elevat on thereof as wardly lrom the forwardportion 01 the seat 1 6 is an arm 11, the lower l'orked end or whichSAMUEL BARR, subjects o'l' the King of Great 1 Britain, residing in thecity and county of embraces one end 01' a lever 12 which is l'ulcrumedon a bracket 13 rising from a hori zontal partition 1 1 within thecasing. The other end of the lever 12 extends to a position adjacent amovable member 15 oi a registering device 16 which may be 01' any commenand well known construction, which operates to register each time itsmovable member is moved. The movable member may be connected to anindicating hand or number 01 indicating hands geared together andoperatively connected to its movable member. These registering devicesare common. and well known, and no detailed description thereo'l' isdeemed necessary herein. The lever 12 is held in engagement with the arm11 by a spring 17 secured to the lever Thus it will be seen that eachtime the seat 6 is depressed a person occupying the chair, and israisedby the action of the spring 10 upon the removal of the person, thelever 12 will act upon the member 15 of the registering device 16 toregister the occupation of the seat.

It sometimes happens that the occupant of the seat is restless, and doesnot keep enough pressure upon the seat 6 to maintain it depressed at alltimes. In order to prevent more than one operation upon the register ngdevice for each time the seat is occupied, due to the restlessness 01'the person, we provide the 'l'ollowing: Risin from the projection 14 isbracket 18 to which is pivoted a bell top 8 oi the step 3 is pivotallyconnected to crank lever 19, one end of which is provided with a hook20, and the other end of which is connected to the upper end of a rod 21which. extends down through the casing, and has its lower end connectedto one arm of a bell crank lever 22 which is pivotally mounted on abracket 23 rising from the bottom of the casing. The other arm of thebell crank lever 22 is pivotally connected to a rod 24 which extends toand is connected to one arm of a bell crank lever 25 pivoted to abracket on the inside of the front wall of the step The other arm of thelever 25 is provided with a roller 26 which engages a plate on thebottom of the top of the step 3 to maintain said step slightly normallyelevated by the action of a spring .ZZseeured to the rod 24 and the rearwall of the casing. Projecting downwardly from the seat 6 adjacent thehook 20 is a bracket 26 carrying a roller 29 which is so located withrelation to the hook 20 that when the seat 6 is depressed the hook 120may pass over and into engagement with said roller to maintain the seatin the depressed position. The moment the weight of a person depressesthe seat 5, the hook 20 moves into engagement with the roller by theaction of a spring secured to the bell crank lever 19 and the seat 6.ihus it will be seen that the seat 6 will be maintained in the depressedposition irrespective 01' the restlessness ol' the occupant. Tfhen,however, the occupant leaves the seat and in descending his weight comesupon the top 8 of the step 3, the roller 29 will be depressed, therebymoving the bell crank lever 25,the rod '24, the bell crank lever 22, therod 21, and the bell crank lever 19 in a manner to disengage the hook 20from the roller 29 and permit the sp ing 10 to raise the seat 6 readyfor the reception of the next occupant.

in order to prevent a rapid upward movement of the seat 6 upon itsrelease from the hook 20, we provide a pneumatic cushion comprising acylinder 31 having a piston 32 therein, the cylinder 31 being secured toa bracket 33 rising from the partition 1%. The piston 32 is providedwith a depending rod 3%, the lower end oi which is connected to a yokeframe 35 which extends downwardly from the seat 6. Thus it will be seenthat the piston 32 will be raised and lowered with said seat.

Screwed into tile cylinder 31 above the piston 32 is a block 36 havin anopening 37 therein leading from the interior ol the cylinder to theexterior thereof. Screwed into the block 36 and entering the opening 37is a thumb screw 38 which may be adjusted to vary the size of theopening 37. During the raising of the seat 6 and therewith the piston32, the compression of the air within the top of the cylinder 31prevents the rapid upward movement 01' the seat 6, and during the upwardmovement of the seat the compressed air escapes from the cylinder 31through the opening 37. Thus it will be seen that the upward movement ofthe seat 6 may be nicely regulated by adjusting the screw 38 to vary thecross sectional area of the opening 37 leading from the cylinder.

The front wall of the casing is provided with a hinged door directly infront of the registering device 16 wnereby access may be had to theinterior of the casing for the purpose ol read ng the registering deviceand for other purposes, including the disengagement oi the link from thepin d3 to permit the raising of the seat 6 beyond its usual limit forpurposes of repair, &c.
